Peanut Butter Jelly Time originated with a flash animation that showed a Banana dancing wildy about the screen rapping the following lyrics: "Peanut Butter Jelly Time Peanut Butter Jelly Time(repeats several times), Peanut Butter Jelly with a baseball bat, Peanut Butter Jelly with a baseball bat."

Use it in moments of extreme silliness, Like when class starts or something.
